CARCASS'SCRAPING-,AND POLISHING- MACHINE.

Speciicationof Letters Patent. Patented Dec. 26,1911.

Application filed July 1, 1907. Serial No. 381,815.

To all .whom t may concern.'

Be it known that I, JOHN W. KoHLHErP, a citizen of the United States,and a resident of Chicago, Cook county, Illinois, have invented certain.vnew and useful Improvements in Carcass -Scraping and PolishingMachines; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to the.accompanying drawings, and to the letters of reference marked thereon,which form apart of this specification. l

This invention relates to improvements in carcass scraping and polishingmachines of that class in which the carcasses are delivered past andinoperative relation with beaters and Scrapers, and are turned orrotated while operated on by said beaters and Scrapers.

The invention belongs to thefsame class as my prior inventions set forthin my applications for patents led on the 18th day of May, 1906, SerialNo. 317,451, and on the 29th day of March, 1907, Serial No.

365,416, In those v.applications the car' casses were suspended andmoved past ro tative beaters and Scrapers and rotated; during theirpassage and the object of this invention is to provide a scraping andpolishing device adapted for use for large or small butcheringestablishments. In either event the carcasses are passed substantiallyhorizontally through the machine and mechanically rotated while operatedupon by the beaters.

It is a further object of the invention to provide mechanism forrotating the carcasses during their passage along the beaters therebybringing all parts of the carcasses into position to be thoroughlycleaned and polished.

.It is a further object of the invention to provide a casing orreceptacle to confine the steam or vapor due to the scalding Vof thecarcasses and to jet upon the carcasses a hot spray during the scrapingand polishing operation. I

Finally itis an object of this' invention to provide an exceedinglycheap, simple, durable and effective mechanism of the class describedcapable of operating effectively upon a single `carcass while passingtherethrough, or as effectively operating upon a continuous line ofcarcasses delivered comparatively rapidly therethrough.

Theinvention embraces many novel features and consists of the mattersherein aftery defined and more fully pointed out in the drawings.

In the drawings; Figure 1 is a yvertical longitudinal section of a-device embodying my .invent-ion. Fig. 2 is'a section thereof on line2--2 of Fig. 1. Fig. 3 is a fragmentary top plan view of the chute forreceiving the carcasses from the machine and the conveyer for deliveringthe hair and other refuse laterally. .Fig. 41 is an enlarged transversesection ofthe beater shafts. Fig. 5 .is a similar view showing chainsemployed as beaters. Fig. 6 is an enlarged detail of one of the spraypipes. Fig. 7 is a trans- .verse section with parts omitted andillustrating the drivefor the cylinder.V

As shown on the drawings: A, A. and A2 g indicate frame members orstandards constructed of cast metal or any suitable material and asshown, each aording at the top on opposite sides thereof-bearings forroll.- ers a upon whichis supported a cylinder B of relatively largesize in which rotates the beater'shaft C and through which in operativerelation with the beater shaft, the carcasses are successively passed.Said stand# ards are of a height to support said cylinder with itsdischarge or vrear end lower thanits receiving end, and as shownextending peripherally around the cylinder'in position to receive therollers therein are channels a7 which by engagement at each end of saidrollers act to holdlthe cylinder from horizontal movement whilerotating.`

At the receiving end of the cyli der .is provided a peripheral rimbhaving sprocket teeth thereon adapted t`o be engaged by a sprocket wheelc of a size to .permit the beater shaft to be rotated in the same oropposite direction to the rotation of the cyl-` inder but at a vmuchhigher rate4 of speed. Within the cylinder as shown are inclined arebeams a3 on which is journaled angle iron ribs b4 which extend spirallylaround the same to assist in delivering car casses therethrough. The.rateof delivery of course is determined bythe 'rate of rota- .ing ofsuch ply and width as to afford a very stiff section. Said sections care of a length to extend to near the inner periphery of the cylinderand are provided with Scrapers c2 on the end thereof preferably directedin the direction of the rotation of the-carcasses. A bolt c3 extends'through said shaft through facing blocks CJ'clo and,

through a relatively short section of the belting c* and a washer c5rigidlylbinding `all to the shaft. Said'washer c5 as shown is a castingor plate one end of which projects towardmthe scraping end of the bladeand is'curved"'utwardlyl'as shown in Fig. 4, so that the belt when bentba'ek-wardly in striking is resisted bythe short belt sec?"A tion c'Land said bent end of the washer preventing a short bend thus tending toprevent the belt from breaking. In the construction shown in Fig.' 5 acollar c is secured on the shaft in any suitable manner and is providedwith oppositely directed lugs c7 to which are secured. a plurality ofchains cs which are of the same length as the beater lor belt sectionsand serve substantiallyl the same purpose. Conveniently also the facingblocks 0--010 are tapered toward the .discharge end of the cylinder,thus inclining the belt transversely thereofl in the direction of thelength of the cylinder and in consequence to a certain extent strikingthe carcasses in a manner to assist in propelling them toward thedischarge end.

rIhe tank I) may be directed in any suit"- able manner for scaldingpurposes and supplied witli water of a suitable temperature lin anysuitable manner. Extending thereinto and driven continuously or in anysuitable manner is the belt conveyer Z which elevates the carcasses fromthe tank D and delivers the same thereover down the chute d into thecylinder. At the discharge end ofthe tank is a chute e which inclinesfrom the cylinder and ythe end of which adjacent the cylinder isconstructed of a plurality of slats spaced a suflicient distance apartto pei'- mit the hair and other refuse to fall therethrough asy the hogslidesv down the incline'.

. Extend-ing transversely the cylinder beneath the slide is a beltconveyer c operated con` tinuously in a suitable manner and which actsto convey the hair and other refuse laterally from the machine. Beneaththe ccnveyer positioned to receive the water driven from the cylinderand through the slats, and conveyer, is the tank E supplied with hotwater in any convenient manner. This tank is piped to a force pump E'from which disthe cylinder and longitudinally therof, and is providedas shown with perforated sections ct through which the spray is workedupon the carcass in the bottom of the cylinder.

The operation is as follows: By the use of considerable power thecylinder and the shaft are rotated continuously' and the conveyers d ande are Aalso continuously driven. The cylinder is driven peripherally andthe beater shaft rotated in the same or opposite direction, the cylinderhowever, rotating much more slowly than the beater shaft as thecarcasses are carried upwardly on one side of the cylinder the ribs b4therein assisting in turningthe carcasses 'against the action of thebeaters or with the action of the beaters depending upon the rotation ofthe cylinder. The carcass as rotated is of course exposed /to lthelaction of the beaters and Scrapers on the shaft and the inclined websor beaters serve together with the spirall ribs and theinclination ofthe cylineiid. Of course it is quite immaterial so cerned if buta'single\liog is within the cylinder, or if the carcasses lie inIcontinuous lines each close to the other and of course ishing effect onlthe carcasses will be the same if one or many are deliveredtherethrough in a given time. Of course too, the rate of travel throughthe cylinder may be increased if the cylinder is lengt-hened and forsmall slaughter houses or where but few carcasses are operated upon in aday, a comparatively shortl cylinder may be used and the carcassesdelivered therethrough more slowly.

Ofcourse it is evident that details of construction may be varied and Ihave not attempted to show more than one manner of embodying myinvention.
